如何将逗号分隔的字符串拆分为数组并再次用冒号拆分该数组？

Question

我有一个字符串，用逗号分隔。我已经使用 explode 用逗号分隔它，这给了我数组形式的结果。在那个数组中，我有需要用 : 分隔的数据。我怎样才能做到这一点？下面是字符串和输出。

字符串：

$ing= 'coconut water :3-4 cups, coconut flesh : ½ cup, tea :4 tablespoon, Ice cubes :24-32, Lemon juice :4 tablespoon, Honey :8 tablespoon'
$output = explode(',', $ing);

输出：

Array ( [0] => coconut water :3-4 cups 
    [1] => coconut flesh : ½ cup 
    [2] => tea :4 tablespoon 
    [3] => Ice cubes :24-32 
    [4] => Lemon juice :4 tablespoon 
    [5] => Honey :8 tablespoon )

现在，我想要单独的椰子水：3-4 杯冒号。

$ing= 'coconut water :3-4 cups, coconut flesh : ½ cup, tea :4 tablespoon, Ice cubes :24-32, Lemon juice :4 tablespoon, Honey :8 tablespoon'
$output1 = explode(',', $ing);
$output=array();
foreach($output1 as $item){
  $output[]=explode(':', $item);
}

输出：

Array
(
[0] => Array
    (
        [0] => coconut water 
        [1] => 3-4 cups
    )

[1] => Array
    (
        [0] => 
coconut flesh 
        [1] =>  ½ cup
    )

[2] => Array
    (
        [0] => 
tea 
        [1] => 4 tablespoon
    )

[3] => Array
    (
        [0] => 
Ice cubes 
        [1] => 24-32
    )

[4] => Array
    (
        [0] => 
Lemon juice 
        [1] => 4 tablespoon
    )

[5] => Array
    (
        [0] => 
 Honey 
        [1] => 8 tablespoon
    )

)

期望的输出：

<tr>
  <td>coconut water </td>
  <td>3-4 cups</td>
</tr>
<tr>
  <td>coconut flesh</td>
  <td>½ cup</td>
</tr>
<tr>
  <td>tea </td>
  <td>4 tablespoon</td>
</tr>
<tr>
  <td>Ice cubes</td>
  <td>24-32</td>
</tr>
<tr>
  <td>Lemon juice</td>
  <td>4 tablespoon</td>
</tr>
<tr>
  <td>Honey</td>
  <td>8 tablespoon</td>
</tr>

Answer 1

如果您在使用 explode 后遍历数组，您也可以使用 explode 以冒号分隔值（数组的值）。

Answer 2

请尝试：

$ing= 'coconut water :3-4 cups, coconut flesh : ½ cup, tea :4 tablespoon, Ice cubes :24-32, Lemon juice :4 tablespoon, Honey :8 tablespoon'
$output1 = explode(',', $ing);
$output=array();
foreach($output1 as $item){
    $output[]=explode(':', $item);
}

要显示段：

foreach($output as $row){
   //insert a new row here:
   echo '<tr>';
      //fill cells in row:
      echo '<td>'.$row[0].'</td>';
      echo '<td>'.$row[1].'</td>';
   //close the row:
   echo '</tr>';
}

Answer 3

请试试这个..这可能有用:)

$ing= 'coconut water :3-4 cups, coconut flesh : ½ cup, tea :4 tablespoon, Ice cubes :24-32, Lemon juice :4 tablespoon, Honey :8 tablespoon';
$output = explode(',', $ing);

function getBetween($content,$start,$end) {
    $r = explode($start, $content);

    if (isset($r[1])){

        $r = explode($end, $r[1]);
        return $r[0];

    }
    return '';
}


    foreach ($output as $value) {
        # code...

            $value = $value.'_!!_';
            $data = getBetween($value,':','_!!_');
            echo $data = str_replace('_!!_','',$data);
            echo '<br>';
    }

Answer 4

$ing = 'coconut water :3-4 cups, coconut flesh : ½ cup, tea :4 tablespoon, Ice cubes :24-32, Lemon juice :4 tablespoon, Honey :8 tablespoon';

$lines = explode( ',', $ing );

foreach( $lines as $line ) {
    $item = explode( ':', $line );
    $tablerow[] = '<td>' . $item[0] . '</td><td>' . $item[1] . '</td>';
}

echo '<table><tr>' . implode( '</tr><tr>', $tablerow ) . '</tr></table>';

如何将逗号分隔的字符串拆分为数组并再次用冒号拆分该数组？

How can I split a comma delimited string into an array and again split that array by colon?

php
